I actually started that thread back then, mainly to tell other tank enthusiasts about my country's tanks and to learn about theirs. There had been enough discussions about well-known tanks like Panthers or Shermans, lesser-known tank types need to be talked about too.

They look like the Hungarian AT rocket system - 44M Buzogányvet's rocket

They are, or at least the ones on the Toldi. The Mace-launcher was a heavy, shaped-charge AT missile with enough payload to damage or knock out basically everything the Soviets had at the time. Unfortunately only a few dozen were made, they were used mostly around the siege of Budapest. There was an anti-infantry variant too called "Zápor" (flurry/heavy rain) with canister warheads. The ones on the Zrínyi are standard Nebelwerfer-pods. The Zrínyi might be the same Zrínyi I prototype that is known as the only one that existed.

Neither versions were known to have been deployed in combat. Although I'm curious how they would have worked out. The Toldi was a fast and agile light tank and Buzogányvetős packed a serious punch; it makes sense to combine the two. Although such a combination is far more difficult in practice than in theory and by the end of the war the Hungarian military had little time or resources to refine a concept into a well-tested weapon.

Pfeifenkopf (also called Pinsel)
Conceived as an anti-tank guided missile using a visual homing system based on the principle of television. The missile was to carry a super-iconoscope in it’s head using a spiral scanning method, which compared the missile’s own target image with that from it’s aiming device. The crude imaging system using as it's basis the target’s contrast with it’s background.
Unfortunately, due to the crude technology in use, this method demanded that a very sharp contrast had to exist between the target and the background, something that could never be guaranteed on the battlefield.
Tests carried out in late 1944, however, proved the system fairly successful, and it was proposed that development of Pfeifenkopf should also include a capacity for air-launching as an air-to-ground missile for tank hunting.
Pfeifenkopf weighed about 25 kg, and had a projected range of a little over 1,000 metres.
The Pfeifenkopf project also led to another anti-tank missile proposal, Steinbocke, which was very similar in design, but used an infra-red homing device instead of the visual homing of Pfeifenkopf.

The X-7 Rotkäppchen (Red Riding Hood) was a anti-tank missile. Designed and developed by Ruhrstahl AG in 1943, After the Heereswaffenamt (Army Ordnance Board) placed an urgent order for anti-tank missiles, this project was under the leadership of Dipl.-Ing. Max Otto Kramer.
The X-7 Rotkäppchen (Red Riding Hood) This weapon was intended to be deployed against tanks and armoured vehicles. Dipl.-Ing. Max Otto Kramer had been experimenting since early 1938, with remote control freefalling bombs, and in 1940. Kramer joined Ruhrstahl AG.

The X-7 Rotkäppchen (Red Riding Hood) was shell shaped body had two wins at its aft end with parabolic leading and trailing edges and two small pods for the wire link spools were attached to the wing tips, spoiler control was simplified on the X-7 Rotkäppchen by the installation of only one spoiler on an extended curved arm. The rocket motor used was 1 × WASAG 109-506 solid fuel rocket engine producing up to kg of thrust. The wire link control system was employed for the X-7 Rotkäppchen which used Düsseldorf FuG 510 transmitter and the Detmold FuG 238 receiver, also a radio controlled system was planned for the X-7 Rotkäppchen using the FuG 203/230h. detonation was achieved by use of an impact fuse.

A few hundred X-7 Rotkäppchen were produced atRuhrstahl AG Brackwede factory however there were unconfirmed reports of the X-7 being used operationally on the eastern front, and it appears that this missile was extremely effective. Even against the heavy armoured, Stalin tanks.

I read that it was 2.5-3kg presented as a shaped charge with a stand off denonator in the cone.

With the shaped charge of that size and the following weight of the rocket motor it would NOT have to fall on the top....any hit would be a critical hit even on a tank made by the myitical WoT Red Pixels makers

The first prototype was followed by a larger production model with a changed detonator for the shaped charge of 2.5 kg. The back part of the main body (length 46.5 cm; diameter 15 cm)contained the two-stage solid fuel rocket engine 109-506 developed and made by the company WASAG. The wings were swept forward and had wingtips which housed the guidance wires, wingspan was 60cm. The small elevator/steering rudder assembly was set off 13.2 cm of the main body's axis. Total length including the protruding detonator cap (diameter: 3.8 cm) was 95cm. The fully loaded Rotkäppchen weighed 9kg.
The missile was to be launched from a start rail tripod that was 150cm long and weighed 15kg. the missile's rocket engine was ignited with a 300V battery. This fired the 2g gunpowder positioned in the two hollow half rounds of the gyro stabilizer. the explosion gases exited through two tangential openings and immediately brought the gyro to operating speed. Then the 3kg of propellant of the first stage of the rocket engine were ignited. They developed 68kp thrust and accelerated the missile to it's flight speed of 98m/s in 2.5 sec.

Watch it bounce off a T50 and an IS8 every time but kill every Brit tank it hits:)

Remember the Hungarian rockets were just Werfer-Granate 21 air 2 air rockets ( http://www.ww2aircra...erstorer.jpg )with a large shaped charge fitted and fired from a tube/launcer.
Because of the good design of the venturi they had some degree of "acceleration/time/range" predictibility and thus could be a good AT system. (all be it short range).

The Rotkäppchen was Wire Guided. Much was made during the cold war with the guidance systems and concepts by all nations.
